Resumo: In this essay, we address, in a tentative and tangential manner, the ways in which the sciences are called upon to manifest themselves at the heart of a UNESCO Candidature process for the Chapada do Araripe to be recognised as a ‘mixed heritage site’.This process is based, ipso facto, on an enormous depth of geological and palaeontological time and subordinates it to the continuity and preservation of its ‘natural’ and ‘cultural’ aspects in the present and future. According to UNESCO criteria, created in the 21st century, ‘mixed heritage’ specifically refers to the association or inseparability of these aspects. We consider that this specific candidature process (which we have called, for brevity, the Chapada candidature, or just the candidature) has an anti-confiscatory appeal, that is, of resistance and alternative to the various confiscations that are now under way in the Chapada region, and to the pitfalls that heritage institutions and policies may imply in this sense. In this regard, we suggest the tendency towards the destratification of thought that emanates from the candidacy. As with any other candidature for UNESCO certification, there are some confiscatory processes associated with the Chapada candidature, but we will not discuss it in this text.
